[more][less]Abstract: The enzyme 11β-hydroxysteroid dehydrogenase (11β-HSD) interconverts active glucocorticoids and their intrinsically inert 11-keto forms. The type 1 isozyme, 11β-HSD1, predominantly reactivates glucocorticoids in vivo and can also metabolise bile acids. 11β-HSD1-deficient mice show altered inflammatory responses and are protected against the adverse metabolic effects of a high-fat diet. However, the impact of 11β-HSD1 on the composition of the gut microbiome has not previously been investigated. We used high-throughput 16S rDNA amplicon sequencing to characterise the gut microbiome of 11β-HSD1-deficient and C57Bl/6 control mice, fed either a standard chow diet or a cholesterol- and fat-enriched ‘Western’ diet. 11β-HSD1 deficiency significantly altered the composition of the gut microbiome, and did so in a diet-specific manner. On a Western diet, 11β-HSD1 deficiency increased the relative abundance of the family Bacteroidaceae, and on a chow diet, it altered relative abundance of the family Prevotellaceae. Our results demonstrate that (i) genetic effects on host–microbiome interactions can depend upon diet and (ii) that alterations in the composition of the gut microbiome may contribute to the aspects of the metabolic and/or inflammatory phenotype observed with 11β-HSD1 deficiency.

[more][less]Abstract: To examine systematically factors that contribute to the efficacy of nutrition education interventions in promoting behavior change for good health based on their stated objective. In a departure from previous reviews, the researchers investigated factors that lead to success of various types of interventions. Critical analysis of these factors constituted the outcome of this review. URI: http://repository.daystar.ac.ke/xmlui/handle/123456789/2960 Files in this item: 1

[more][less]Abstract: Volunteerism in America could be considered a national pastime with nearly 1 in 4 Americans, an estimated 62.6 million people, serving as volunteers according to the National and Community Service report.1 Volunteerism includes a wide range of activities undertaken to serve others or contribute to a cause of common good for the general public where monetary reward is not the driving factor, according to the general assembly of the United Nations.2 The Society for Nutrition Education and Behavior (SNEB) as an organization would never achieve its stated goals without the many hours and skills provided by its member volunteers.

[more][less]Abstract: This qualitative study explored factors associated with causes of food insecurity including cultural factors and coping strategies among rural Hispanic population in west Texas. A sample of 20 participants from low-income households participated. Coding and analysis of the key themes were done by four independent coders. Four overarching themes emerged: (1) food insecurity is a well-kept secret and is a cultural aspect, (2) behavioral and environmental elements are major causes of food insecurity, (3) coping strategies and the price of staying food secure, and (4) strategies for plausible interventions to food insecurity. Positive coping strategies included buying in bulk, buying when items are on sale, and cooking and eating at home, while increasing the volume of food by making food soupy, buying starchy inexpensive food and only eating beans and rice might compromise the nutritional value of the diet. This study underscores the importance of studying the cultural aspect of food to inform interventions addressing food insecurity.

[more][less]Abstract: Abstract Context Establishing healthy dietary practices at an early age is crucial, as dietary behaviors in childhood track to adulthood. Objective The purpose of this systematic review was to identify factors associated with successful nutrition education interventions conducted in children and published between 2009 and 2016. Data Sources Using the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines, relevant studies were identified through the PubMed, Web of Science, ScienceDirect, and ERIC (Educational Resources Information Center) databases. Study Selection Studies published in English between 2009 and 2016 that included a nutrition education intervention among children aged 2 to 19 years were included. Review articles, abstracts, qualitative or cross-sectional studies, and studies targeting children with special nutritional needs were excluded. Data Extraction Four authors screened and determined the quality of the studies using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system and extracted the data from the articles. Data Analysis Forty-one studies were included: 7 targeted preschool children, 26 targeted elementary school children, and 8 targeted secondary school children. A total of 46% met their primary objectives of nutrition education intervention, while the rest either partially achieved or did not achieve their stated objectives. Results Successful interventions targeting school children engaged parents by means of face-to-face sessions, identified specific behaviors to be modified, and assured fidelity by training teachers or recruiting trained experts to deliver the intervention. In addition, they allowed adequate dosage, with an intervention duration of at least 6 months, and used age-appropriate activities. Conclusions Interventions with a multicomponent approach that were age appropriate and of adequate duration (≥ 6 months), that engaged parents, and that ensured fidelity and proper alignment between the stated objectives, the intervention, and the desired outcomes were more likely to succeed.

[more][less]Abstract: The notion of quality is hard to define precisely, especially in the context of tertiary education where institutions have broad autonomy to decide on their own visions and missions. Any statement about quality implies a certain relative measure against a common standard; in tertiary education, such a common standard does not exist. Various concepts have evolved to suit different contexts ranging from quality as a measure for excellence to quality as perfection, quality as value for money, quality as customer satisfaction, quality as fitness for purpose, and quality as transformation (in a learner) (SAUVCA 2002). Some institutions have adopted the International Standards Office (ISO) approach in some of their activities. Depending on the definition selected, quality implies a relative measure of inputs, processes, outputs or learning outcomes. Institutions, funders, and the public need some method for obtaining assurance that the institution is keeping its promises to its stakeholders. This is the primary goal of quality assurance. The leadership of the quality assurance directorates in universities has therefore come into sharp focus. URI: http://repository.daystar.ac.ke/xmlui/handle/123456789/2837 Files in this item: 1

[more][less]Abstract: Family meals are associated with significant benefits including increased dietary quality,1 4 reduced risk behavior for substance abuse3 5 and disordered eating behaviors,3,4 improved cognitive performance among children,3 5 and strengthened family connectedness.4,5 Promoting healthy eating through family meals is suggested to be an important public health strategy, but family mealfocused interventions that educate entire families are lacking.6 Furthermore, family programs that promote healthful family mealtimes through an experiential and observational learning environment for underserved families within a community setting are limited or not widely reported. The objective of Let’s Cook, Eat, and Talk (LCET) was twofold: to promote healthy eating behaviors by providing combined nutrition education and cooking classes to underserved families in the community setting and to facilitate family mealtime communication to strengthen family relationships among participants in East Lubbock, TX.
